Abstract: Systems, methods, and circuits provide passively Q-switched laser systems operable to emit a pulse train that is synchronized to a reference clock operating at a relatively high pulse repetition frequency. Such pulsed laser systems can include a gain medium; a pump source that excites the gain medium into a higher energy state; a passive Q-switch; a photodetector that produces an electronic signal synchronous with the laser output pulse; and an electronic control system that inputs the signal from the photodetector and controls the pump source to optimize the synchronization between the output laser pulses and a reference clock. The clock source may be internally generated by the electronic control system or input externally. In some examples and embodiments, passively Q-switched lasers can be utilized as transmitters in automotive LIDAR systems.
